Voltaic \Vol*ta"ic\, a. [Cf. F. volta["i]que, It. voltaico.]
1. Of or pertaining to Alessandro Volta, who first devised
apparatus for developing electric currents by chemical
action, and established this branch of electric science;
discovered by Volta; as, voltaic electricity.
2. Of or pertaining to voltaism, or voltaic electricity; as,
voltaic induction; the voltaic arc.
Note: See the Note under Galvanism.
Voltaic arc, a luminous arc, of intense brilliancy, formed
between carbon points as electrodes by the passage of a
powerful voltaic current.
Voltaic battery, an apparatus variously constructed,
consisting of a series of plates or pieces of dissimilar
metals, as copper and zinc, arranged in pairs, and
subjected to the action of a saline or acid solution, by
which a current of electricity is generated whenever the
two poles, or ends of the series, are connected by a
conductor; a galvanic battery. See Battery, 4.
(b), and Note.
Voltaic circuit. See under Circuit.
Voltaic couple or element, a single pair of the connected
plates of a battery.
Voltaic electricity. See the Note under Electricity.
Voltaic pile, a kind of voltaic battery consisting of
alternate disks of dissimilar metals, separated by
moistened cloth or paper. See 5th Pile.
Voltaic protection of metals, the protection of a metal
exposed to the corrosive action of sea water, saline or
acid liquids, or the like, by associating it with a metal
which is positive to it, as when iron is galvanized, or
coated with zinc.

Element : \El"e*ment\, n. [F. ['e]l['e]ment, L. elementum.]
1. One of the simplest or essential parts or principles of
which anything consists, or upon which the constitution or
fundamental powers of anything are based.
2. One of the ultimate, undecomposable constituents of any
kind of matter. Specifically: (Chem.) A substance which
cannot be decomposed into different kinds of matter by any
means at present employed; as, the elements of water are
oxygen and hydrogen.
Note: The elements are naturally classified in several
families or groups, as the group of the alkaline
elements, the halogen group, and the like. They are
roughly divided into two great classes, the metals, as
sodium, calcium, etc., which form basic compounds, and
the nonmetals or metalloids, as oxygen, sulphur,
chlorine, which form acid compounds; but the
distinction is only relative, and some, as arsenic,
tin, aluminium, etc., form both acid and basic
compounds. The essential fact regarding every element
is its relative atomic weight or equivalent. When the
elements are tabulated in the order of their ascending
atomic weights, the arrangement constitutes the series
of the Periodic law of Mendelejeff. See Periodic law,
under Periodic. This Periodic law enables us to
predict the qualities of unknown elements. The number
of elements known is about seventy-five, but the gaps
in the Periodic law indicate the possibility of many
more. Many of the elements with which we are familiar,
as hydrogen, carbon, iron, gold, etc., have been
recognized, by means of spectrum analysis, in the sun
and the fixed stars. Based on certain evidence (as that
afforded by the Periodic law, spectrum analysis, etc.)
it appears that the chemical elements probably may not
be simple bodies, but only very stable compounds of
some simpler body or bodies. In formulas, the elements
are designated by abbreviations of their names in Latin
or New Latin. The Elements

Element :
1. One of the items of data in an array.
2. One kind of node in an SGML, HTML, or
XML document tree. An SGML element is typically
represented by a start tag ("") and an end tag (" ").
In some SGML implementations, some tags are omissible, as with
"" in HTML.
The start tag can contain attributes (""), which are an unordered set of key-value
bindings for that element. Both the start tag and end tag for
an element typically contain the "tag name" (also called the
"{GI" or generic identifier) for that element.
In XML, an element is always represented either by an
explicit start tag and end tag, or by an empty element tag
' alt='a dodad' />").
Other kinds of SGML node are: a section of character data
("foo"), a comment (""), a markup declaration
(""), or a processing instruction
("").
